CLOTH-TAKE-UP MOTION FOR LOOMS.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 5. 1906. Serial No. 304,358.

engineer, have invented certain new and useful 1mprovements inOloth-Taking-Up Motions for Looms, for which application has been madein Great Britain, No. 5,128, dated 11th March, 1905.

This invention relates to means or mechanism for drawing through ortaking up the cloth as it is woven in weaving looms.

The object of the present invention is to make a taking up mechanismthat will weave any pick required without changing any wheels.

In order that the invention may be clearly understood, reference will behad to the accompanying drawings, in which Figure 1 is a sectionalelevation of the mechanism; Fig. 2 is a section taken on the line AAlooking to the left; Fig. 3 is a section of Fig. 1 on the line BBlooking to the right; Fig. 4 is a section of Fig. l. on the line CClooking to the right; Figs. 5 and 6 are elevation and plan view,respectively, of the mechanism as a whole; Figs. 7 and S are twodiagrammatic views showing the adjustments hereinafter referred to; and

Fig. 9 is an enlarged detail view of the free-wheel devices shown inFig. 3.

2 represents a pawl carrier which acts upon the catch wheel 3, which bymeans of intermediate gear acts upon the draw or sand roller 4. Thecatch wheel 3 is mounted on a stationary shaft 4 and carries aplurality, say {1, of small pinions 5, which gear into a small pinion onthe sleeve 6 loose on the shaft 4.. These small pinions 5 have shafts 7bearing in the catch wheel 3 and arranged as shown in Fig. 2 with cranks8 connected to eccentric rods 9 working on an eccentric 10 which is partof a circular index plate 11, and mounted on an eccentric part 12 of theshaft 4. The eccentricity of the part 12 of the shaft and of the part 10is such that by the index plate 11 being turned round on the part 12,the center of rotation for the eccentric rods 9 can be broughtconcentric with the shaft 4. The small pinions 5 are mounted on theshafts 7 as free wheels by means of the usual spring actuated roller andslot clutch, such as 13 (Fig. 3). Ro tatably mounted on the sleeve 6 isa frame 14 which carries a pinion 15, which gears with teeth 16 on thesleeve 6. Integral with the pinion 15 is a smaller pinion 17 which gearswith further pinion 18 mounted on the shaft 4 which is provided with afurther pinion 19. On the part connecting the pinions 18 and 19 and alsorigidly connected to the frame 14 is a second catch wheel 20. The pinion19 gears with the sand or draw roller wheel 21.

Connected to the frame of the loom 22, in which the shaft 4 is rigidlymounted, is a support 23 which carries two pawls 24 and 25, which engagewith the two catch wheels 20 and 3 respectively. The pawl-carrier 2 isrevolubly mounted on the sleeve 6 and actuated from any suitable part ofthe loom in the ordinary way. In close proximity to this pawl-carrierand revolubly mounted on the sleeve 6 is a cam 26, on the surface ofwhich'an arm 27 rigidly connected to the pawl 28 of the pawl-carrierslides. This cam is adjustable on the sleeve 6, and capable of beingfixed in any suitable position by some such clamping device as thatindicated as 29. The cam is provided with a shoulder 30 which can beadvanced or set back so as to regulate the position in which the pawl 28will engage with the teeth of the catch wheel 3 in the oscillation ofthe pawl-carrier, so that the catch Wheel can be rotated one, two ormore teeth as desired at each oscillation.

The circular or index plate 11 is capable of being clamped in any givenposition by means of a clamp 31 secured to any suitable fixed part ofthe loom, such as indicated by 32. This clamp 31 also acts as astationary indicator, under which the index plate is moved.

The operation of the device is as follows :The index plate is adjustedso that it shows the desired number of picks per quarter inch. Thisadjustment will alter the relative eccentricities of the part 10 and theshaft i, and as small shafts 7 connected to the pinions 5 areconcentrically arranged about the shaft 4, will also alter theeccentricity of the part 10 relative to these shafts 7 (see Figs. 7 and8). On the pawl carrier being set in motion it will urge forward thecatch wheel 3 a given amount for each oscillation, the amount beingcapable of regulation as described by means of the cam 26. The turningof the catch wheel 3 about the cam 10 will cause, as will be seen fromFig. 2, the'oscillation of the shafts 7 to an amount corresponding tothe position of the part 10. The pinions 5 being mounted as free wheelson the shafts 7 will only be moved forward in one direction see Fig. 9),and in the present case as they gear with teeth on the sleeve 6, willforce round this sleeve in advance of the catch wheel 3. The sleeve 6communicates its motion by its teeth 16 to the reducing motion comprisedby-pinions 15, 17, 18 and 19, so that the draw or sand roller wheel 21is given a slow forward motion. The second catch wheel 20 is normallyheld stationary by its pawl 24, but is capable, on the pawl 24 beingreleased, of being rota-ted by hand, whereby motion' can be communicatedto the pinion 19 through pinions 15, 17 and 18, so that the sand or drawroller can be quickly adjusted by hand to any given position, and ifrequired turned back in case any mispicks have been made in the loom.This second catch wheel is rendered necessary owing to the impossibilityof moving the first catch wheel 3 backwards, which is prevented by thefree wheel motions connected with the pinions 5.

It will be obvious that if it is desired to lessen the number of picksto the quarter inch in the cloth, the

motion of the draw or sand roller will have to be accelerated. When thisis desired all that is necessary is to alter the circular index plateI]. so as to bring a higher number opposite the index 31, which actionwill increase the eccentricity oi the part 10 relative to the shaft 4,and so increase the throw of the cam and the motion of the pinions 5.

I declare that what I claim is:

1. In a cloth taking up motion for looms, a draw or sand roller, acentral shaft, a catch wheel mounted on said shaft, a sleeve on'saidshaft, pinions concentrically mounted in said catch wheel and gearingwith said sleeve, suitable gearing between said sleeve and said draw orsand roller, and means for rotating said pinions relative to said catchwheel.
